water injection

I was just wondering if a water injection thread has been started before.
It seems like alot of people are kind of lost to the concept.
If it hasn't been done, i could start a thread in with all of the information needed (this usually applies to forced induction cars, so that is where the thread will be).

Theres a nice alky/water injection thread in the racing non specific section, I've been doing some research on setups to raise boost with and increase horse power, for the future I think I'm going to go meth+H2O injection and reworked 13t turbos, I have a lot of mods to do before that though. A guy on 3SI just started selling an injection kit for $210 but its not a variable spray type like I think I'll get.

his kit is the same thing from www.turbomirage.com if you want to take the time to build it yourself and save a few bucks
